LUBRICATOR.

Specification of Letters Patent.

Patented June 19, 1906;

Application filed April 4, 1905. Serial No. 253,821.

To LY/ZZ whom, it may concern;

Be it known that I, BURT O. KELLY, a citizen of the United States, residing at Petroleum, in the county of Wells, State of Indiana, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Thisinvention relates to lubricators, and more particularly to lubricators for gas-enines, and has for its object to provide a ubricator which will include a water-jacket and an oil-reservoir, the water-jacket being arranged to receive heated water from the cooling system of the engine to maintain the oil at a low temperature.

Another object is to provide a lubricator which will include a sight-glass through which the amount of oil fed to the cylinders may be seen and which will also include means for preventing the passage of pressure from the cylinders to the oil-reservoir.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a side elevation of the present invention, illustrating a portion of a gas-engine to which it is attached. Fig. 2 is a longitudinal section of Fig. 1, taken through the valves and oil-passage. Fig. 3 is a section on line 3 3 of Fig. 2 and illustrating the relative positions of the water-chamber and oil-reservoir. Fig. 4 is a top plan view.

Referring now to the drawings, the present invention comprises a hollow body portion 5, including side walls 6, 7 8, and 9, a bottom 10, and a removable top 11.

A horizontally-extending partition 12 is located within the body portion and lies in spaced relation to the bottom 10 this partition terminating short of the wall 8 and lying in engagement with the other walls. Extending upwardly from the edge of the partition 12 ,which lies adjacent to the walls, there is a vertical partition 13, which at its side edges meets the walls 7 and 9 and lies m engagement with the top 11 at its upper end. There are thus formed an oil-reservoir 14 and a water-chamber 15-, the latter extending at one side and beneath the former.

The bottom 10 has a vertical threaded opening 16 therein, in which there is engaged a pipe 17, which is connected with the overflow-pipe 18 of the water-jacket 19, which surrounds a gas-engine cylinder 20. The bottom 10 also has a downwardly-extending stem 21 at its center which has an angular passage 22 formed therethrough and opening through its lower end and one of its sides, and this stem is threaded at its lower portion, as shown at 23, the threaded portion being engaged in an opening 24, which communicates with the cylinder 20.

Engaged in the end 25 of the passage 22, which opens through the side of the stem 21, there is a pipe 26, which extends laterally and which has an enlarged head 27 at its outer end, this head having a vertical passage 28 formed therethrough and communicating with the interior of the pipe 26. Engaged in the lower end of the passage 28 there is a removable plug 29, which closes this end of the passage, and extending upwardly from the head 27 there is a hollow exteriorly-threaded stem 30, which surrounds and communicates with the upper end of the passage 28. Connected with the stem 30, by means of a packing-collar 31, there is an upwardly-extending sight-glass 32, the upper end of which is engaged in the packing-collar 33, carried by a needle-valve 34. This needle-valve is provided with a downwardly-directed outletopening 35, which communicates with the sight-glass 32, and this outlet-opening is surrounded at its upper end by a valve-seat 36 arranged for the reception of a tapered head 37 of an upwardly-extending and verticallymovable valve-stem 38. As will be seen from the drawings, the stem 38 may be moved downwardly to engage its head 37 in the valve-seat 36 to close the-opening 35, upward movement of the stem bringing it out of engagement with the valve-seat, and means (indicated at 39) is provided for moving the stem. The stem is also adjustable to lie at different distances from the valve-seat when it is in inoperative position. The needle-valve 34 is also provided with a laterally-directed opening 40, which communicates with the interior of the oil-chamber 14 for the passage of oil through the needlevalve and the portions connected therewith to the cylinder 20.

Extending from the stem 21, oppositely from the pipe 26, there is a nipple 41, the passage through this nipple communicating with the passage 22 and registering with the passage through the pipe 26. At the inner end of its passage the pipe 26 has a valve-seat. 42, and at the outer end of the nipple 41 there is a stuffing-box 43. A valvestem 44 is slidably engaged in the nipple 41 and extends outwardly through the stuffing-box 43, this stem having a handle 45 at its outer end by which it may be moved, and the stem is held yieldably at the outward limit of its movement by means of a helical spring 46, engaged with the stem between a circumscribingflange 47,

formed thereon, and an inwardly-directed flange 48, carried by the inner end of the nipple 41; but the stem 44 is movable against the action of the spring 46 to bring its tapered inner end 49 into engagement with the valve-seat 42, thus closing the pipe 26. The stem 44, adjacent to its inner end, is provided with a surrounding flange 50, the edge portions of which are curved toward the pipe 26, and it will thus be seen that should any back pressure from the cylinder 20 enter the passage 22 this pressure striking flange 50 will move the valve-stem 44 into position to close the passage through the pipe 26, thus preventing the pressure from entering the oil-reservoir.

The oil-reservoir 14 is provided with an opening 51 in one of its sides, this opening being covered by a piece of glass 52, through which the amount of oil in the reservoir may be seen.

The water-chamber has an outlet-opening A adjacent to its upper end.

What is claimed is A lubricator comprising a body portion having an oil-reservoir therewithin, a downwardly-extending stem carried by the body portion, said stem having laterally and vertically communicating passages therewithin and being adapted for connection of its vertical passage with the cylinder of a gas-engine, a horizontal pipe engaged in the lateral passage, connections between said pipe and oil-reservoir for the passage of oil from the reservoir to the pipe, said pi e extending into the stem and having a va ve-seat at its inner end, a valve-stem slidably engaged in the first-named stem at the opposite side thereof from the horizontal pipe and adapted for movement to bring its inner end. into engagement with the valve-seat to close the horizontal pipe, a spring arrangedto hold the valve-stem yieldably out of operative position and a flange carried by the valvestem and extending toward the horizontal pipe, said flange being adapted to receive pressure thereagainst to move it toward the pipe and to bring the valve-stem into position to close said pipe.

In testimony whereof I aflix my signature in presence of two witnesses.
